DataStore script not saving correctly?

I'm making a datastore that saves both money and gears. I started testing the datastore by seeing if it saved money, and it didn't save money. When the players had no save data, though, it set their money value to 520 like the script should do.

Basically my issue is that the script always sets money's value to 520, even if I change the money value to something like 1000 and leave the game. I want it to set the money value to 1000 when I leave the game, not 520. Here's my scipt:

local DataStoreService = game:GetService("DataStoreService")
local ds = DataStoreService:GetDataStore("ToolSave")
local ds2 = DataStoreService:GetDataStore("MoneySave")

game.Players.PlayerAdded:connect(function(Player) --When the player joins the game, load value.

    local Stats = Instance.new('Model')
    Stats.Name = "leaderstats"

    local Money = Instance.new('NumberValue',Stats)
    Money.Name = "Money"

    Stats.Parent = Player


    --load data
    local moneyData;
    local toolData;

    local CanSave = Instance.new('BoolValue', Player)

    CanSave.Name = "CanSaveData"
    CanSave.Value = true

    local DataFetchSuccess, ErrorMessage = pcall(function()
        moneyData = ds2:GetAsync(tostring(Player.UserId))
        toolData = ds:GetAsync(tostring(Player.UserId))
    end)
    if DataFetchSuccess then 
        if moneyData ~= nil then --This could be where the problem is
            Money.Value = moneyData
        else
            Money.Value = 520 -- Where money value is changed to 520
        end
        print(Money.Value)
        if toolData ~= nil then
            for i,v in pairs(toolData) do
                print(v)
                local tool = game.ServerStorage.Tools:FindFirstChild(v)
                if toolData then
                    toolData:Clone().Parent = Player:WaitForChild("Backpack")
                    toolData:Clone().Parent = Player:WaitForChild("StarterGear")
                end         
            end
        end
    else
        Player.CanSaveData.Value = false
        Player:Kick("Your data failed to load! Please rejoin.")
    end
end)

game.Players.PlayerRemoving:connect(function(Player) -- When the player leaves the game, data must save.
    if Player.CanSaveData.Value == false then return end - -[[There could also be a problem with saving the money--]]

    local moneyData = Player.leaderstast.Money
    local toolsToSave = {}

    for i,v in pairs (Player.Backpack:GetChildren()) do
        if v then
            table.insert(toolsToSave, v.Name)
        end
    end

    local DataWriteSuccess, ErrorMessage = pcall(function()
        ds:SetAsync(tostring(Player.UserId), toolsToSave)
        ds2:SetAsync(tostring(Player.UserId), moneyData)
    end)

    if not DataWriteSuccess then
        local Retry_Count = 0

        while Retry_Count < 6 do
            wait(60)
            local Succeed, Error = pcall(function()
                ds:SetAsync(tostring(Player.UserId), toolsToSave)
                ds2:SetAsync(tostring(Player.UserId), moneyData)
            end)
            if Succeed then break end
            Retry_Count = Retry_Count + 1
        end
    end
end)

Thank you!
